  • Patent number: 7263804
    Abstract: A vehicle door, wherein a drive unit for raising and lowering a glass plate is constructed so that a plurality of pulleys across which wires are laid are provided at upper and lower sides of a base panel. The glass plate is moved up and down by driving the wires, and the glass plate is prevented from moving in a vehicle inward direction when the door is closed. Wire fixing portions are prevented from being damaged by large upward and downward stroke movements of the glass plate Furthermore, the wires are prevented from slackening when the wires are driven and stopped by providing a supporting rod along a path of upward and downward movement of the glass plate, and a contact member which has no contact with the supporting rod. Trumpet-shaped guide portions are provided at hole edges of the wire fixing portions, and the V-shaped circumferential surfaces of a tensioner eliminates slack in the wires.

  • Patent number: 7234274
    Abstract: A vehicle door drive unit for raising and lowering a glass plate is constructed so that a plurality of pulleys across which wires extend are provided at upper and lower sides of a base panel. The glass plate is supported by a carrier plate which is connected to the wire ends. The glass plate is moved up and down by the wires and is prevented from excessively moving in a vehicle inward direction when the door is closed by a supporting rod positioned along an upward and downward path of the glass plate and a contact member. Trumpet shaped guide portions are formed at the edges of holes of the wire fixing portions of the carrier plate and the circumferential surfaces of a V-shaped tensioner are provided for eliminating slack in the wires.

  • Patent number: 4917489
    Abstract: A light beam spot size measuring device comprises an optical magnifying system. The magnifying system receives an image of the recording light beam spot formed within an optical recording apparatus, and magnifies it. Then the converter receives the magnified image of the beam spot formed on the pickup surface thereof so as to produce an output signal representing the size of the beam spot. An attenuator device attenuates the intensity of the image of the laser beam spot during magnification. The image of the beam spot therefore can be currently measured on the basis of the output signal even with the high intensity of the recording light beam.

  • Patent number: 4864470
    Abstract: A surface acoustic wave (SAW) device is mounteed in such a manner that its functional surface faces a base plate and a space is formed therebetween to avoid inferiority in device characteristics. Electrodes of the SAW device and bumps formed on electrodes at predetermined positions of the base plate are connected to each other by applying pressure and heat to secure electrical continuity. A peripheral surface of the SAW device is bonded to the base plate by an adhesive to seal the functional surface of the SAW device.

  • Patent number: 4627725
    Abstract: A device for monitoring the amount of deviation of a light beam in an optical system with which the freedom of design of the system is significantly improved. For each position at which the amount of deviation is to be measured, a beam splitter is provided to divide the light beam at that point into a main beam and a sub-beam. The sub-beam is applied to an optical position detector which detects the amount of deviation of the sub-beam from a predetermined position on the detector, that deviation being related to the amount of deviation of the main beam from its designated optical path. The output of the position detector is used to correct the position of the main beam.

  • Patent number: 4408319
    Abstract: An optical information recording disc having pits in a first film formed on one of major surfaces of the disc is uniformly covered with a suitable second film, whereby the size of each pits is corrected. When the disc is to be used as a mother disc for production of replicas, at least the wall of each pit is covered by a third layer having continuously increased thickness towards the bottom of the pit so that a peeling off of an intermediate transfer disc from the mother disc is facilitated.
